FURNACE Specification of Letters Patent.

Patented Feb. 23, 1909.

To all whom it may concern:

Be it known that we, PHILIP B. HEoKLER and LoUIs J. HEcKLER, citizens ofthe United States of America, residing at Sheraden, in the county ofAllegheny and State of Penn sylvania, have invented certain new anduseful Improvements in Furnaces, of which the following is aspecification, reference being had therein to the accompanying drawing.

This invention relates to hot air furnaces and its primary object is, toprovide a furnace having an extended radiating surface to insure athorough circulation of the incoming cold air and a consequent heatingthereof before it reaches the outlets.

A further object of the invention is to provide a hot air furnace with arevoluble radiator to facilitate the connection therewith of thedischarge flue pipe.

A further object of the invention is to im prove the details ofconstruction of this class of furnaces.

The construction of the improvement will be fully described hereinafterin connection with the accompanying drawing which forms a part of thisspecification, and its novel features will be defined in the appendedclaim.

In the drawing ;-Figure 1 is a view in perspective of a'furnaceembodying the invention, the shell'or casing and other parts of thestructure being broken away to show the interior construction, and, Fig.2 is a horizontal section on the line 2-2 of Fig. 1.

The reference numeral 1 designates the cylindrical shell or casing ofthe furnace provided at its base with a cold air inlet 2. The top 3ofthe shell is of the usual tapering contour, and provided with radiallydisposed hot air outlets 4.

Within the base of the shell is arranged a gas burner 5 of any approvedconstruction, connected to a gas supply pipe 6. A conical hood 7 fitsover the burner 5, said hood resting on suitable cleats 8 secured to thewalls of the furnace shell, and having a tubular outlet 9 at its apex.

The radiator comprises two cylindrical cup-shaped members 10 and 11, onearranged within the other and the inner of said members being of suchdiameter and such height with respect to the outer of said members as toform a heating space. Interposed between the body portion of saidmembers is a partition 12 which divides the heating space. The partition12 is formed with an opening 13 for the passage of the products ofcombustion from the upper to the lower portion of the heating space. Thepartition 12 also constitutes a brace for the body portions of saidmembers so as to retain them apart. The heating space between saidmembers is closed at its top through the medium of a flat ring 14 whichis formed integral with the top of the body portion of each of themembers. The bottom (if the inner member is indicated by the referencecharacter 15 and that of the outer member by the reference character 16,the same bottom being provided with openings 17, the openings in thebottom 15 alining with the openings in the bottom 16 and said aliningopenings are connected by short pipes 18.

Depending centrally from the bottom 16 of the outer member of theradiator is a pipe 19 which communicates with a central opening 20 inthe said bottom 16, and also fits upon the pipe 9 of the conical hood 7,the fitting between the pipe 19 and. 9 being in the form of a slip jointand by such manner of connecting the pipes 19 and 9 together it permitsof the radiator being turned to bring its discharge flue opening 21 intoalinement with the flue pipe 22 for connecting the flue 21 with the fluein the wall of a building.

The shell 1 of the furnace is adapted to be provided with an opening atany desired point to receive the flue pipe 22.

The operation of the furnace constructed as thus described will bereadily understood. The products of combustion are confined by the hood7 and pass therefrom through the pipes 9 and 19 into the heating s )aceformed between the two members of tie radiator circulating within saidspace being baffled by the partition 12, and finally escaping throughthe opening 13, and the upper ortion of the space between the radiatorshe ls to the discharge flue 22. Cold air entering through the pipe 2first circulates around the conical hood, and then around the outermember of the radiator and through the pipes 17 to the interior of theouter member, finally passing out after being thus thoroughly heated,through the pipes 4, leading to the apartments to be heated.

Itwill be observed that the improved construction affords an extendedarea of heating surface over which the incoming air passes before itreaches the distributing hot air pipes, and hence a thorough heating ofthe air is insured.

As the discharge flues in buildings are frequently located at pointswhere the back of approximately centrally the ends of said para furnacecannot be conveniently connected tition being spaced from each otherwhereby therewith, the adjustability of the radiator to adapt its flueopening to be alined with the discharge flue at any point is a featureof importance.

Having fully described our invention what we claim as new and desire tosecure by Letters Patent, is

In a hot-air furnace, the combination with the shell thereof, of aburner arranged at the bottom of the shell, transversely extendingsupports for said burner, a conical shaped hood arranged over the burnerand provided with a vertically-extending discharge pipe at the apexthereof, an air inlet at the bottom of the shell, a radiator arrangedwithin the shell in close proximity to the top thereof and embodying twocylindrical cu shaped members, one arranged within the other, said innermember of such diameter and of such height with respect to said outermember as to form a heating space between the two members, a fiatcircular partition arranged in the vertical portion of said heatingspace communication is established between the upper and lower part ofthe vertical portion of the heating space, means for closing the upperend of the vertical portion of the heating space, and slip ointconnection between the hood and the radiator, said connectionestablishing communication between the interior of the hood and theheating space, means extending through the bottoms of said members forestablishing communica tion between the interior of the inner member andthe space below the bottom of the outer member,-means for establishingcommunication between the heating space and the atmosphere, and a seriesof distributing pipes projecting from the top of said shell. 11testimony whereof we afiix our signatures in the presence of twowitnesses.
